not to keep repeating myself, but the truck blocked the car
the car hit the truck
traffic was moving slow, and the truck could have simply been merging
picture if you're making a right hand turn, and halfway thru the turn, a driver tries to come up underneath and just guns it. If the car hits the truck, who's fault is it?
now, if the truck had hit the car in some sort of PIT maneuver, then the driver would totally be at fault.
and, again, the car had plenty of time and room to stop.
